  • Publication number: 20080097151
    Abstract: An endoscope processor comprising a touch-panel monitor, a location detector, a touch-panel image generator, and a location-changer, is provided. The endoscope processor displays an image of a target area with enlargement on a monitor. The target area is a part of a captured entire image. The location detector detects an input location. The input location is a location where the user's input operation is done on the touch-panel monitor. The touch-panel image generator orders a target-area location window to be displayed on the touch-panel monitor. The target-area location window indicates the location of the target area in the entire image. The location-changer changes the location of the target area based on the input location detected by the location detector when the target-area location window is displayed.
